Tawkon, an app designed to minimize your exposure to cellular radiation, so you can continue using your cell phone safely and responsibly. It's available for Blackberry, Android, and iOS, provided you're willing to jailbreak your phone to get it. Is safety from radiation worth falling from Cupertino's good graces?

Unless you were in a coma (and if you were, we hope you're feeling better now,) you'll recall that last month the media and consumer ballyhoo surrounding the iPhone 4's antenna woes came to a head. At the heart of the issue was the fact that if users held the smartphone in a certain manner that's now come to be affectionatly known as the Death-Grip, the phone would lose a significant amount of signal reception due to a design flaw. In a now legendary email, Steve Jobs suggested that users simply not hold their phones "that way." Well, if dropped-calls and lousy connections weren't reason enough to consider doing just that, an Israeli software company has another you can add to the list: Holding your mobile in a death-grip ups the handset's radiation level.
